New York City’s transit authority has released photos of a device fraudsters used to skim credit card information from commuters buying metrocards from a vending machine.

The perpetrators installed their own card reader in the machine, and then glued a hidden camera above the machine to record patrons punching in their pins. The camera was disguised as an electrical outlet.
